1 Claim. 1

This invention relates to a convertible hair brush designed to adapt it for use in connection with hair re-curling after brushing.

An object of this invention is to provide a resilient mounting for hair re-curling implements on hair brushes whereby implements of diiferent sizes or modifications may be removed and replaced.

Another object of this invention is to provide a resilient mounting for an elongated brush carried implement made of plastic and normally breakable material whereby the resilient mounting absorbs the shock when the brush isdropped and the implement yields under strain due to impact.

Another object of this invention is to provide a replaceable resilient connecting device made of an open coil spring which will withstand repeated handling for a considerable period of time.

With the above and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawings and pointed out in the claims which form part of this specification.

Reference will now be had to the drawings, wherein like numerals of reference designate corresponding parts throughout the several views, in which:

Figure 1 is a side elevation of a convertible hair brush embodying the invention, and showing a handle in cross-section.

Figure 2 is a side elevation of a hair re-curling implement which is threadable into unitary relation with the hair brush, the implement being partly broken away to how a resilient thread member molded therein.

Figure 3 is an end view of the implement shown in Figure 2.

Figure 4 is a view showing the opposite end of the implement shown in Figure 2.

Figure 5 is a side elevation of a modified resilient hair re-curling implement.

Figure 6 is an end view of the implement shown in Figure 5.

In the illustrated embodiment of the invention, the numeral l0 indicates a convertible hair brush comprising a brush body H which is preferably made of plastic material and which carries bristles l2 separated into tufts l3 and suitable for hair brushing.

The hair brush It! has an enlarged circular shank M which is internally threaded at l5. The shank [4 has an end portion it of smaller diameter than the diameter of the remainder of the 2 shank. The end portion thread 11.

An implement l8 of elongated form for recurling the hair after brushing is threadably secured to the shank M. The implement l8 has a circular end portion t9 and tapers substantially to a point at the free end portion 20.

In practice it is found desirable to use difierent sizes of hair re-curling implements, and the threaded ends of the implements permit removal and replacement or interchangeability of the recurling implements.

It is also found in practice that hair brushes are frequently dropped, and, due to the rigidity of the plastic material of which the implements must be made, they would break off from the brush body.

To prevent this breakage, we provide a resilient mounting which absorbs the shock when the brush is dropped and the implement yields under strain due to impact.

As shown in Figures 3 and 4, the re-curling implement l8 has a male wire thread 22 molded in the plastic material of which the implement is made.

The wire thread 22 is made in the form of an open coil spring and project-s outwardly from the large end portion of the implement I8 sufficiently to engage the internal thread ['5 in the body of the brush in positive engagement and hold the brush body H and the implement It in unitary relation without danger of accidental displacement.

The implement it! has a body 23 of generally rectangular cross-section and a cylindrical portion 24 extending from the circular end portion l9 to the end of the thread.

It is to be noted that the wire spring 22 is positioned in axial alinement with the brush body II. It is also to be noted that the brush body I I is of relatively small extent between the sides thereof so that it may be easily gripped in the hand of the user to function as a handle in the manipulation of the hair re-curling implement iii.

In operation, the resilient wire thread 22 is interenegaged with the thread I5 in the brush body and when the implement strikes an object, the thread 22 permits lateral movement and return of the implement to the alined position.

A substantially cylindrical handle 25 has an elongated aperture 25 and a closed end 21. The aperture 26 is of a size to receive the implement l8 into concealment therein.

The handle has an internal thread at one end adapted to engage the thread I! on the brush l6 has an external body H.

The handle is of considerable cross-section, the threaded end being of the same diameter as the circular shank portion M of the body II.

The adjoining ends of the handle and brush body are designed to butt against each other and provide a rigid support for the brush under forcible treatment.

It is to be noted that the handle 25 is unscrewed from the brush, when it is desired to utilize the implement [8.

Figures 5 and 6 show a modified resilient recurling implement 30 comprising a tapering solid plastic body 3| of rectangular cross-section and terminating in a circular end 32, similar to the end I9 in the implement I 8.

The implement 30 has a solid threaded end portion 33 which interengages with the thread l5. We provide a spring wire 34 which is imbedded in the plastic material substantially throughout the length of the implement 3B. The spring wire absorbs the shock when the brush is dropped and the implement is forced to yield under strain due to impact. The implement 30 thus comprises the threaded portion 33 which is resilient and functions substantially like the wire thread 22 in the implement 18.

In accordance with the patent statutes we have described and illustrated the preferred embodiments of our invention, but it will be understood that various changes and modifications can be made therein without departing from the spirit of the invention as defined by the appended claims.

We claim:

In a hair brush having a longitudinally positioned female thread at one end thereof, a resiliently reinforced implement permitting human hair to be re-curled thereon, said implement having a resilient male wire thread at one end, causing axial alinement of said implement with said brush, said resilient thread being engageable with said female thread and permitting lateral displacement and return of said implement to said alined position, said implement tapering substantially to a point and being of reduced cross-section, said resilient implement thread permitting removal and replacement of said implement, the end of said brush body adjacent said implement thread having a male thread of larger diameter than said implement thread, and a hollow cylindrical handle having an elongated aperture of a size to receive said implement thread into concealment therein, said handle being closed at one end and having a female thread at the opposite end engageable Withsaid male thread on said brush body for engagement therewith, said handle having an end wall adapted to butt against said brush body and providing a rigid support for said brush under forcible treatment thereof.
